g = range(100)print(g)g = (r for r in g)print(g)g = list(g)print(g)

输出:

range(0, 100)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57…省略]

解释:首先,我们创建了一个range(100)对象,这是一个生成器,表示从0到99的整数序列。然后,我们使用生成器表达式将其转换为一个新的生成器对象,并打印了它的结果。最后,我们将这个生成器对象转换为一个列表,并打印了结果。通过这种方式,我们可以逐步查看数据的转换过程。
